That's what the BTR was talking about. Trying to recall a phone conversation from a year ago lol. BTR doesn't make a custom gear to delete the phaser for the 220 cam and a LS3 timing set would set the cam ~8.5 degrees advanced, and I swear he said there is advance already in the cam grind, so you'd have to do the math on valve timing. Either way, you'd be chopping off a nice chunk of top end range just to delete the phaser. Better to just run a cam spec designed for a phaser delete than try to force the 220 to bend to your will, LOL.
I still think OP should try to juice up the oil pressure a bit and see if the Phaser behaves better. Should be able to swap in some 15w50 if you can't get 5w50 locally. 15w50 is track spec. If it helps stabilize, then it's a good fix. If not, it could be a bad phaser perhaps. The spring should have enough tension to keep the phaser at rest, and the cam spins in favor of the direction of rest, if the cam is coming off "0" it's getting fed oil and/or the spring doesn't have enough tension to keep it at rest. Would have to compare datalogs with someone who has the BTR cam w/limiter and "not" having issues. See desired cam angle and actual cam angle on that log, in both normal driving and WOT conditions. I have a feeling most that are running the limiter see similar conditions with cam angle doing its best to maintain desired but it's not perfect. If someone can post a log showing desired and actual cam angle in lock-step with each other, then I guess I have a problem, too. LOL
